Assume that a sample is used to estimate a population mean mu . Use the given confidence level and sample data to find the margin of error. Assume that the sample is a simple random sample and the population has a normal distribution. Round your answer to one more decimal place than the sample standard deviation. 95% confidence; n =12; x overbar =

In a regression analysis, a residual plot is: Select one: a. A scatter diagram that plots the values of the residuals against the values of the dependent variable. b. A scatter diagram that plots the values of the residuals against the values of an independent variable. c. A histogram that plots the frequency of certain value ranges of the
